Product Description
66L CO₂ (5%), CH₄ (50% LEL), and O₂ (16%) Calibration Gas – IR, LEL & Oxygen Deficiency Testing
This 66L custom calibration gas cylinder is designed for multi-gas detector calibration requiring mid-range CO₂ accuracy, combustible gas verification, and oxygen-deficiency simulation.
The mixture includes 5.0% Carbon Dioxide (CO₂) for IR (NDIR) sensor calibration, 2.5% Methane (50% LEL) for standard combustible gas testing, and 16.0% Oxygen (O₂) to simulate reduced oxygen environments.
This blend is ideal for confined space monitoring, safety compliance testing, and detector validation under low-oxygen conditions.
